Speccaton of Letters Patent.

Patented Nov. 28, 1905.

Application filed August 29. 1904. Serial Nox 222,649.

State of Illinois, citizens of the United States,

have invented certain new and useful Improve- 'ments in Lamps, of whichthe following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

This invention relates to lamps adapted to be set within the wall of arailway-car and may be designated as a panel-lamp.

It consists of a suitable frame adapted to be secured to the surface ofthe wall and incloses an aperture therein, a double back projectingwithin the wallaperture and containing an air-chamber, and a front sohinged to the frame that the hinges are not visible, together with meansfor introducing the illuminant into the chamber of the lamp.

The invention consists, further, in various details of construction, ashereinafter described and as illustrated in the accompanying drawings,in which Figure l is a central vertical section of the lamp, taken on aplane extending from front to rear. Fig. 2 is a plan section on the line2 2 of Fig. l. Fig. 3 is a detail section on the line 3 3 of Fig. 2; andFig. 4 is a detail front elevation of the lamp, partly in section.

A portion of the inner wall of a railwaycar is indicated at 10 10, anaperture being provided therein to receive the back of the lamp. Theattaching-frame of the lamp comprises the bottom member 9, the side bars11, and a cap 12. The side bars 11 are provided with instandingapertured lugs 11, as shown in Fig. 4, by means of which the lamp may besecured to the wall of the car by means of screws, and as these lugs areinclosed within the lamp body the attaching means are not observable.The bottom member is secured to a bracket 13, which is in turn attachedto the wall 10 of the car. The sidebars 11 are riveted at their lowerends to upstanding lugs formed on the bottom member 9 and at their upperends to depending lugs from the cap 12, and they are also provided withinstanding apertured lugs, through which screws may be passed into thewoodwork of the car-wall. The iinial 14 is shown as attached to the topof the cap 12.

The back wall of the lamp 15 is preferabljT of sheet metal formed toproject inwardly through the aperture in the car-wall and having flanges16 and 17 at its bottom and top, respectively, for engagement betweenthe corresponding members of the lamp-frame and the wall of the car.

The front 18 of the lamp bows outwardly, being shown as comprising threefiat panels,

and fits when closed against the several mem- C bers of the frame. Thisfront is carried by a pair of link-hinges 19 20, pivoted at their innerends by means of a pin 21 to hinge-lugs 22 23, projecting inwardly fromthe side members 11 of the lamp-frame, and at their outer ends to lugs24 25, projecting inwardly from the lamp-front and atits vertical medianline. The pintle 26 securing the lower hinge-link 19 to the lamp-frontserves also as a bolt for engaging a suitable socket in the bottom 9 ofthe lamp to retain the front in its closed position. This pintle isconsequently arranged to slide vertically and is spring-depressed, asuitable thumb-piece being shown for raising it suiiiciently todisengage it from the socket of the lamp-bottom.

The reflector 27 is preferably of sheet metal and is bowed inwardly, soas to project through the aperture in the wall of the car, but is spacedapart from the back 15, so as to provide an air-chamber 28 coextensivewith the back of the lamp. At its upper end the reiiector curvesforwardly and terminates in the cap 12, which is apertured, as shown at81, to

'allow the escape of the vapors of combustion and also provide forcirculation through the air-chamber 28. The strong current of vapor fromthe combustion-chamber induces a iiow of air through the chamber 28 andassists in f keeping therear wall of the lamp cool.

The back 15 may have side flanges, as 29 30, which lie between the sidemembers 11 of the lamp-frame and the wall of the car. The side edges ofthe reflector are preferably continued forwardly beyond the line of thesurface of the car-wall and will shade the joint between the sidemembers of the frame and the wall, so that if a close tit is not securedlight will not be emitted. The reflector is shown as secured by means ofscrews 37 passing' into the woodwork of the car-wall.

A duct 32 leads from a suitable aperture in the bottom 9 of the lamp tothe chamber 28, so as to provide it with a supply of cool air. Thebottom 9 is further apertured to supply IOO air for combustion when gasis used as an illuminant, and these apertures are preferably covered bylight-shades 33.

When gas is used as an illuminant, it may be introduced into the body ofthe lamp by means of a pipe 35A, entering through its back, and which isshown in the present instance as provided with an acetylene-gas burner36.

As thus constructed the lamp may be secured to the wall of a carentirely by means of hidden screws, the bracket 13 having an upstandingwall-plate, which is covered by a footpiece of the bottom 9, restingupon the sole of the bracket, to which it is secured. The hinges of thelamp-front are entirely inclosed within the body of the lamp, and hencenot visible.

The comparatively cool current of pure air issuing from the chamber 28mixes with the vapors as they issue from the combustionchainber. Ittherefore not only immediately dilutes the carbonic-acid gas due tocombustion, but also lowers its temperature, so that it will not injurethe decorations of the car, thus rendering it feasible to make the frontof the lamp approximately flush with the wall. This cooling action makesit possible also to employ decorative effects in connection with thelamp which involve the use of readilyfusible materials, such as leadsettings for the glass.

We claim as our invention- 1. As an article of manufacture, a lampcomprising a chambered body portion having a transparent front andopaque back and a laterally-projecting wall-plate intermediate of itsfront and back, a burner within its bodychamber, and a discharge-flueleading from the combustion-chamber forward of the wallplate.

2. As an article of manufacture, a chambered lamp-body provided with alaterallyprojecting wall-plate and having its back cxtended back of suchplate, and a discharge-fine leading from the combustion-chamber forward.

3. As an article of manufacture, a chambered lam p-body having alaterally-projecting attaching-plate and bowing backwaidly and forwardlyfrom such plate and having a dischargefiue leading from thecombustioncharnber forward of the wall-plate.

4. In a lamp, in combination, a back wall, a reiiector forward of andspaced apart from the back wall and terminating at the top within thebody of the lamp, and an air-duct leading to the bottom of the chamberinclosed between the back wall and the reiiector.

5. In a lamp, in combination, an attachingframe; a double back extendingrearwardly from the frame and comprising a rear wall and areflector-plate, such members being spaced apart to form an air-iiue;and a front attached to the frame and having a bottom apertured tosupply air to the fiue.

6. In a lamp, in combination, an attachingframe, a back, pivoted linksconnected to the side of the frame, and a front connected to the ends ofthe links by means of lugs on its interior.

7. In a lamp, in combination, a lamp-bodyadapted to be secured to a walland to extend within the same, and having double back walls containingan air-fine such ue opening at its lower end through the bottom of thebody and at its upper end within the body.

8. In a lamp, in combination, a lamp-body adapted to be secured to awall and to extend within the same, and having double back walls and anapertured cap, such walls inclosing an air-flue and the forward wallterminating below the cap whereby an opening for the airflue is providedwithin the cap.
